batsman tied July i4, 190e. serai No. 326,233.

is provided an auxiliary bottom disposed'- within an envelop andconnected, through the bottom of such envelop,with an exterior member,by means'of which a conduit or conduits without the envelop is connectedto andfcommunicates with a 'conduit or conduits within the envelop. Theenvelops are preferably of lead, separated by insulatingl material,While the auxiliary bottom and the exterior member are preferably ofhard rubber, vulcanized together through holes in the bottom of theenvelop, so that a iirm, tight, and'insulating construction is produced.

These features and the further improvements of the invention will fullyappean in the-following description and the' accompanying drawings inillustration thereof.

In the accompanying drawings, Figure 1 represents a plan. view of a broen battery embodying the improvements. Fifr. 2 represents a sectionalside elevation of t e same, taken on the line 2 2 of Fig. 1 g and Fig. 3represents a sectional elevation illustrating a second form of theinvention.

Referring to the drawings, the envelops 1,

suitably made of lead,'are separated to pre' vent short-circuiting byinsu ating material 2 disposed between their adjacent walls. Within theenvelops are the auxiliary insulating-bottoms 3, preferably of hardrubber in the form of pans, and supported on the auxiliary bottoms arethe insulating-tubes 4 and 5, preferably of hard rubbervulcam'zed to theauxiliary bottoms.

'As shown in Figs. 1 and 2, the envelops 1 are supported upon theinsulating members 6 ,(preferably of hard rubber) with passages 7therein. The bottoms of the envelops .are provided with apertures 8,through `ywhich the members 3 and 6 are fixed together, as by.vulcanizatiom andl the passages of the tubes 4 and 5 are connected tothe assages of theconduits 6 by nipples 9 -on t e tubes. and passingthrough the auxiliary bottoms p sockets.

and the bottoms of the envelops into sockets 10 of the conduits 6, towhich they are vulcanized. Threaded sockets 11 in the conduits receivethe ends of pipes or conduits 12,-having flanges 12 thereon, and nuts13, sleeved on the pipes, are screwed into the sockets to enga e theflanges and form a tight joint between t ie communicating conduits 6 and12. A

As shown in Fig. 3, the envelops 1 aresupported on the rubber insulatingexterior lmembers 14, vulcanized,fthrough the envelop-openings 8, to theauxiliary bottoms 3.

Conduits 15 are provided with anged branches 1 6, which fit in threadedsockets 17, formed in the parts 14, and nuts 18, sleeved on thebranches, engage the iian es in the Communication is estab ished betweenthe branches. and the interior conduits by passages 19, whose Walls areformed by the vulcanization together of the interior conduits, theauxiliary bottom, and the exterior member.

Porous cups within the envelops have the threaded rubber bushings 21inthe bottorris thereof inregistration. Withthreaded bosses 22 of theconduits 4, and a tubular' coupling 23 is screwed into the parts 21 and22 to connect the cups to the conduits. The cups supported thus and bythe bridges 24 contain the positive electrodes 25 and the solutiontherefor, conducted thereto .and therefrom by the passages described.The spaces exterior to the cups contain the negative 'electrodes 26 andthe solution therefor, carried to and from such spaces by the passagesdescribed.

Having described my invention, I claim- 1'. A battery constructioncomprising a metal envelop having an auxiliary bottom of non-conductingmaterial, a tube within said envelop, and a conduit exterior to vandconnected through said bottom with said tube. 2. A battery constructioncomprising an envelop having a metal bottom, an insulating auxiliarybottom within said envelop,

IOO

nected`v together through an opening in said v metal bottom.

3. battery construction comprising a metal envelop', an ,auxiliaryrubber member within said envelop, and a rubber member exterior'to saidenvelop, said rubbermembers being vulcanized together throgh an openingis said envelop.

4. A battery constructing comprising a' metal envelop, an auxiliaryijottom member of insulating material in the vfyeorm of a pan Withinsaid envelop, and an eiitribrmember of insulating material secured tosaidv bottom member through an opening in said envelop.

5. A battery construction comprising aV pluifflty of metal, envelops,.non-conducting material separatingsaid envelops,` exterior,tothebottomsvof said envelops a non-conducting memberhavinga passageor. passages therein, and each enlvelopa non,-I conducting member with`a passage therein registeringetwitha .passage of said exterior memberthroughlan opening in thebottom of the corresponding envelop.

6. A` battery construction comprising a plurality of metal envelops,non-conducting material separating said envelops, exterior .tothebottoms of .said envelops a n 0n-'con ducting member ormembers withpassages therein, and `a non-conducting conduit or conduits within eachof saidv envelops, each of said conduits having a non-conductingconnection with'v an exterior. nonfconducting member.

7. Avubattery construction comprising a metal envelop, a rubber bottommember a vplurality-.of rubberconduits 'Within eachv I envelop` and.communicating respectivelywithI corresponding'v compartments thereof,andexteriorto said envelops aiplurality of rubber members Withiassagestherein comf municating with sai conduits and vulcanized to said pansthroughopenings in said envelops.
